Find each rate. Counts are sometimes recorded in hundreds: 1/2 hundred steps means 50 steps. Treat each recorded rate as constant within its interval.

Which calculation converts this log to steps per minute?

Step Counter Log
Steps (hundreds)	Time (min)
3/5	1/2

A. (3/5 ÷ 1/2) × 100
B. (3/5 ÷ 1/2) ÷ 100
C. (3/5 × 1/2) × 100
D. (1/2 ÷ 3/5) × 100

A heart-rate sensor counts 2/5 hundred heartbeats in 1/3 minute.

What heart rate does this represent? beats per minute

During a stride calibration, Lina travels 7/8 meter for every 1 1/4 steps. The tracker uses an average step length, so a measurement may include part of a step.
